Finvoice: the Finnish e-invoice standard with one of the highest adoption rates in Europe.
Finvoice is the Finnish standard for e-invoicing and one of the longest-established e-invoice formats in Europe. Finland has one of the highest e-invoicing percentages on the continent: more than 80% of all invoices are exchanged digitally. Finvoice has made a significant contribution to that high adoption rate.
Finvoice is an XML-based invoice format developed by the Finnish banking sector. The format is widely supported by Finnish accounting, ERP and banking software. Unlike formats such as NLCIUS or Svefaktura, which are CIUS variants of EN 16931, Finvoice has its own schema that has historically grown from the Finnish banking infrastructure.
Via the Peppol network, Finnish companies are also reachable internationally. The Finnish PASR (approved September 2025) sets specific requirements for identifiers: only the OVT code (EAS 0216) is permitted for Finnish parties.
Although Finvoice is a proprietary format, Finnish companies are also reachable via Peppol in Peppol BIS Billing V3. Most Finnish parties support both formats. For international invoice exchange, BIS Billing V3 is the recommended route; for domestic Finnish transactions, Finvoice is widely used.
eConnect routes invoices to Finnish recipients automatically via the Peppol network in Peppol BIS Billing V3. Finnish recipients registered on Peppol receive the invoice in the format they support.
